Now we're going to assume that your COR works because you've replaced it and it didn't help. I would next suspect the AFM's ability to turn the COR on. With the afm flapper door pushed in you should see pins 1 and 2 of the afm connector short. These pins on the afm will be mated to by the green with a red tracer and brown wires on the harness connector. you can also test the harness+COR by turning the car to the on position, unplugging the afm connector and shorting the green-red and brown wires together - the fuel pump should run and the COR should click. If you get nothing from that test check to see that pin 2 has 12v from the pin to ground.
